Im looking at getting at slide in camper in the next year or two when I get a long bed tow rig. Any particular models I should look at? I will probably buy used because of the price, and I know that I need to inspect the pop up tracks and canvas. Anybody have any suggestions as far as brands? I would like a shower, but its not neccessary as it will just be me most of the time, maybe the gf once and awhile.
